Topic: Raspberry Pi F.A.Q. (Read 20547 times)

Yes i tried with different adaptators (2.4a, 3a, short cable with good copper quality...), the next time i'll try with the j4 flag.The command is "make -j4" (with a space between)?I've had some problems with my personal ES themes and some updates since the last retropie 4.3.8, however eveything was ok with the 4.3.6. Maybe it come from here...Thanks for your reply.

Hi, effectively the j4 flag is a lot faster! So i tried with the new and the old SFML cmake commands, it's working when i go to attract just after the install but after a reboot, i've some errors like "no file or directory" about libsfml-graphics.so.2.4 and libsfml-windows.so.2.4 files.But the files are in the /usr/local/lib directory. However there were no errors during the install. My firmware is :Linux retropie 4.4.13-v7+ #894 SMP Mon Jun 13 13:13:27 BST 2016 armv7l GNU/Linux

Everything you describe seems to be correct. Are you using a good 2+ amp power adapter? I have seen ffmpeg fail when compiling for no apparent reason. Since it's a new build I would try it again, it might have been a fluke. I'll also mention you can use a "-j4" flag after the "make" commands when you're compiling. This will use all 4 cores of the Pi3 and speed things along.

May I kindly suggest you mention this flag in the first post? Would have been nice to know about before waiting through the hour+ compile!

The -j4 switch isn't mentioned in the first post because it won't work on older versions of the Pi. I only mentioned it when the person posting said he was using a Pi3. The -j4 switch is also less reliable if overclocking is set too high on the Pi.
